i run npp with my sust. and d-bol cycle. i like for the nandrolone to kick in quick. right after i'm done with my first cycle. which is tren. cyp. and drol.
NPP will take over a week to feel. Dbol will kick in for most people in 3 days. And the kick will be much harder from dbol. Deca takes 4 weeks to kick in NPP just cuts that time in half usually.
i did a d-bol, prop. and npp run last year for about 10 weeks and it was kickass. i'd think this would be average.
prop. 150mg/day
npp. 100mg/day
d-bol 60mg./day
